- Comment on What does this emoji mean? Is this a British thumbs up? 1 month ago:
Way way more people use the Shaka to mean Shaka as opposed to call me. If you use that symbol to mean call me, I can’t really help you, but I’ve never actually seen that in real life after like 1995.
Unicode naming can be wrong (and it is here) and that’s ok.
- Comment on Is there a "canvas" of the universe? Do we even know? Would a canvas follow the same laws as the paint? 7 months ago:
No, the analogy is more that the oscillations are themselves the particles.
The addition of energy into a system would be this hand push. The fact that the particles themselves exist means that they are oscillations in this mesh (with some energy/frequency). Interactions with other particles can add or remove energy.
Definitely these canvas metaphor are just conveniences. Also, I got it from Zee’s “Quantum Field Theory in a Nutshell” which is a standard graduate or advanced undergrad level book on QFT.

Special relativity definitely overlaps with quantum mechanics and that overlap forms the basis of the math used at collider experiments like those at the LHC. Special relativity is simple with 2 rules that let you derive all the equations: 1) no universal reference frames 2) speed of light is constant.
You’re probably thinking about general relativity which defines gravity through the curvature of space time.
If you think about quantum mechanics existing on some “canvas”, that might look like an interlocking mesh of springs (like something under a bed or cot). You could take your hand and bounces it up and down on this mesh, adding oscillations and creating standing waves in the grid. These oscillations would be different particles (electrons, protons) each with their own characteristic frequency of oscillations. If you add energy to the bed of springs, you can “pop” particles into existence. All these particles actually are are just excitations of the mesh/canvas. As of yet, there’s been no way to define or find the gravity particle on this canvas, so right now the canvas of space time and the canvas of quantum mechanics are two distinct “things”.
- Comment on Has google stopped working for finding anything? 11 months ago:
I swear people here are either too young or didn’t use the internet 8 years ago. All of this stuff was super common to search and get the first result back as the right answer.

Yes, idiots exist in all contexts. If you gather enough people in one spot, a nice, countable handful will be dumb.

See, though, this is the ignorance that stems from not knowing real life burners. The vast majority (actually none) that I know do not claim anything eco about the event. These people understand what the event is. Don’t lump every one of the 100s of thousands of those who have attended over the years with the handful of social media starlets posting bullshit online. I promise many many people at burning man hate those who post anything about the event on social media.

People are children and repeat what they hear. 15 years ago, I would spout the same nonsense about burning man because of what I read on digg/Reddit from the same voices you hear now. I then met a friend who convinced me to go and I had an absolute blast.
For the vast majority of people in the US, let alone the world, attending the event is almost impossible due to cost, time, materials, etc. - it’s much easier for people that live nearby and most people within driving distance, the views of burning man will be more in line with your views - nuanced and reasonable. If you have no experience and no contact with the regular folks who attend, it’s super easy to bucket people into all these groups.
The reasoning about waste and frivolity is total bullshit — don’t tel me your bullshit vacation to Murtle Beach is anymore eco friendly. Or your plane ride to Bangkok to become more worldly is “green”. Burning man is an event, a vacation. I went many times as a student, spending only about $2000 all in. It’s a relatively economical way to have a blast for a week.

This is a fact of life for all people around the world. I promise you’ll go circles paying retribution if you look for these links of “who stole what”.
